Abstract (en)
Controlled release of a volatile active ingredient, especially an agricultural semiochemical, can be provided by incorporating it during emulsion polymerisation of water insoluble monomeric material in which it is dissolved and which is based primarily on alkyl (meth) acrylates alone or with styrenes, and by appropriate choice of the monomer blend and the Tg of the resultant polymer the rate of release of the active ingredient can be selected.
